Hypermobility Pain: Causes, Associated Conditions, and Management

Why is hypermobility painful?

Hypermobility can be painful because the excessive laxity in connective tissues, primarily ligaments, leads to increased joint instability and stress, causing muscles to overcompensate, resulting in fatigue, microtrauma, inflammation, and sometimes nerve impingement, often compounded by systemic issues like dysautonomia.

Understanding Joint Hypermobility

Joint hypermobility, often colloquially referred to as being "double-jointed," describes joints that can move beyond their typical anatomical range of motion. While some individuals experience hypermobility without pain or significant issues (benign joint hypermobility), for many, particularly those with Hypermobility Spectrum Disorder (HSD) or hypermobile Ehlers-Danlos Syndrome (hEDS), it can be a source of chronic, debilitating pain. This pain is not merely a consequence of "being flexible" but stems from a complex interplay of biomechanical, neurological, and systemic factors.

The Biomechanical Basis of Hypermobility Pain

The primary driver of pain in hypermobility is the inherent laxity of the connective tissues, particularly ligaments and joint capsules, which are designed to provide stability.

• Ligamentous Laxity and Joint Instability: Ligaments, composed primarily of collagen, are meant to act as passive restraints, preventing excessive joint movement. In hypermobile individuals, these ligaments are more extensible or "stretchy." This laxity means joints lack adequate passive support, leading to:

  • Increased Joint Play: Joints move more freely than intended, causing bones to shift or glide excessively within the joint capsule.
  • Microtrauma: Repeated movements at the end-range of motion or beyond can cause microscopic tears and damage to joint tissues, including cartilage, menisci, and the joint capsule itself. This constant, low-level injury triggers inflammatory responses.
  • Subluxations and Dislocations: In severe cases, the joint may partially (subluxation) or fully (dislocation) come out of alignment, which is acutely painful and can lead to chronic instability.

• Muscle Overload and Compensation: To compensate for the lack of passive stability from ligaments, the body's muscular system is forced to work harder to actively stabilize joints.

  • Chronic Muscle Tension and Fatigue: Muscles surrounding hypermobile joints are often in a constant state of contraction to prevent unwanted movement. This sustained effort leads to muscle fatigue, stiffness, spasms, and the development of myofascial trigger points, all of which are painful.
  • Impaired Motor Control: The muscles may become overactive or underactive in specific patterns, leading to muscle imbalances and inefficient movement patterns that further exacerbate joint stress.

• Proprioceptive Deficits: Proprioception is the body's sense of its position in space. Research suggests that hypermobile individuals may have impaired proprioception due to reduced mechanoreceptor sensitivity in lax ligaments and joint capsules.

  • Poor Joint Position Sense: This can lead to individuals unknowingly moving their joints into vulnerable, end-range positions, increasing the risk of injury and pain.
  • Delayed Muscle Activation: Slower or less coordinated muscle responses to sudden movements can leave joints momentarily unprotected, contributing to instability and trauma.

• Inflammation and Degeneration: The chronic microtrauma and increased mechanical stress on joints can lead to persistent inflammation. Over time, this can contribute to:

  • Early Onset Osteoarthritis: The wear and tear on cartilage can accelerate degenerative changes in the joints, leading to pain, stiffness, and reduced function.
  • Tendinopathy: Tendons attaching muscles to bones can become inflamed and painful due to the excessive forces required to stabilize hypermobile joints.

• Nerve Impingement: The increased joint mobility and muscular tension can sometimes lead to nerve compression or impingement, causing neuropathic pain, tingling, numbness, or weakness in the affected area.

Associated Conditions and Contributing Factors

Pain in hypermobility is often multifaceted, influenced by systemic conditions that frequently co-occur.

• Dysautonomia (e.g., Postural Orthostatic Tachycardia Syndrome - POTS): Conditions affecting the autonomic nervous system can cause symptoms like chronic fatigue, dizziness, and widespread pain, which can amplify the experience of musculoskeletal pain.
• Mast Cell Activation Syndrome (MCAS): This condition involves inappropriate activation of mast cells, releasing inflammatory mediators that can contribute to chronic pain, widespread inflammation, and fatigue.
• Chronic Fatigue Syndrome and Fibromyalgia: There's significant overlap between hypermobility and these conditions, which are characterized by chronic widespread pain, fatigue, and other systemic symptoms, suggesting shared underlying mechanisms in some individuals.
• Central Sensitization: Persistent pain signals can alter the nervous system's processing of pain, leading to heightened pain perception and chronic pain states even with minimal stimuli.
• Psychological Factors: Chronic pain is often accompanied by anxiety, depression, and stress. These factors can lower pain thresholds and exacerbate the subjective experience of pain.

Management Strategies for Hypermobility Pain

Effective management of hypermobility pain requires a comprehensive, individualized approach, often involving a multidisciplinary team.

• Targeted Strengthening and Stability Training:

  • Focus on Core Stability: Strengthening the deep abdominal and back muscles provides a stable base for limb movements.
  • Periarticular Muscle Strengthening: Building strength in the muscles immediately surrounding hypermobile joints (e.g., rotator cuff for shoulders, glutes and quads for hips/knees) helps to actively stabilize them.
  • Low-Impact Exercise: Activities like swimming, cycling, and elliptical training minimize joint impact while building strength and cardiovascular fitness.
  • Resistance Training: Using resistance bands, light weights, or bodyweight exercises with controlled, precise movements to build muscle without hyperextending joints.

• Proprioceptive and Neuromuscular Retraining:

  • Balance Training: Exercises on unstable surfaces (e.g., balance boards, foam pads) help improve joint position sense and reactive muscle responses.
  • Coordination Drills: Activities that require precise, controlled movements to enhance motor control and reduce reliance on end-range joint positions.

• Pain Management Techniques:

  • Heat/Cold Therapy: Applying heat can relax tense muscles, while cold can reduce acute inflammation.
  • Manual Therapy: Gentle massage or myofascial release techniques from a qualified therapist can address muscle spasms and trigger points.
  • Medication: Over-the-counter pain relievers (NSAIDs), muscle relaxants, or neuropathic pain medications may be prescribed by a physician.
  • Mind-Body Practices: Techniques like mindfulness, meditation, and yoga (modified for hypermobility) can help manage pain perception and reduce stress.

• Activity Modification and Ergonomics:

  • Pacing: Learning to balance activity and rest to avoid overexertion and subsequent pain flares.
  • Joint Protection: Avoiding hyperextension or "locking out" joints during daily activities and exercise. Using supportive footwear or braces if recommended by a professional.
  • Ergonomic Adjustments: Modifying workstations, seating, and daily tasks to reduce strain on vulnerable joints.

• Multidisciplinary Approach:

  • Physical Therapy: Essential for prescribing tailored exercise programs, teaching safe movement patterns, and providing manual therapy.
  • Occupational Therapy: Can help adapt daily activities and environments to minimize joint stress.
  • Rheumatologist/Geneticist: For diagnosis and management of underlying connective tissue disorders.
  • Pain Management Specialist: For complex chronic pain.
  • Psychologist: To address the psychological impact of chronic pain.

When to Seek Professional Help

If you experience persistent joint pain, frequent subluxations, chronic fatigue, or other systemic symptoms in conjunction with hypermobility, it is crucial to consult with a healthcare professional. A proper diagnosis from a physician, often a rheumatologist or geneticist, is the first step toward developing an effective management plan. A physical therapist specializing in hypermobility can then guide you through safe and effective exercise and rehabilitation strategies.
